An inverse synthetic aperture radar (ISAR) is a radar system capable of forming high-resolution images regardless of weather conditions or light levels. The frequency-modulated continuous wave (FMCW) technique overcomes the system size limitations of pulse-based radars by significantly reducing the analog-to-digital conversion (ADC) sampling rate, consequently increasing the versatility of radar systems, leading to their widespread application in various fields. By separating the transmitter and receiver, bistatic radar can exploit the diverse scattering characteristics of targets and offers advantages such as improved resolution compared with monostatic radar. However, the operation of a bistatic FMCW radar must solve the problem of signal synchronization. This study presents the challenges of bistatic FMCW radar systems, proposes a master–slave structure to address synchronization issues, and demonstrates the formation of ISAR images in real-world scenarios.
